PAUL W. KREUZKAMP, 0F BROOKLYN, NEW YORK, ASSIGNOR TO ENGLANDER SPRINGBED COMPANY, OF BROOKLYN, NElV YORK, A CORPORATION OF NEW YORK.

COLLAPSIBLE BED.

To all whom it may concern Be it known that 1,1PAUL W. KnnUzKAi/ir, acitizen of the United States, residing at Brooklyn, in the county ofKings and State of New York, have invented certain new and usefulImprovements in Collapsible Beds, of which the following is aspecification.

This invention relates to folding beds, it having more particularly todo with the making practical of a certain form of collipsible bed, andit is easier and less dangerous to operate.

In the drawings accompanying and forming part of this specification,Figure 1 is a perspective view of the improved form a of bed with whichthe present improvement has to do, and Fig. 2 is a detailed enlargedview of one corner of the bed showing the same partly folded.

Similar characters of reference indicate corresponding parts throughoutthe figures of the drawings. l

The improved folding bed with which the present improvement has todojcomprises a pair of end frames consisting of a head 2 and a foot 3 towhich is secured brackets 4 having inwardly extending arms 5, the innerends 6 of which are pivotally connected toa mattress frame 7 comprisinga pair of side-bars S to which at the ends thereof is secured transversebars 9 between which the mattress proper 10 is hung. The head and footmembers 2 and 3 are provided with pivoted legs or feet 11, a pair ateach end of the structure being connected or braced by a bar carrycasters or rollers 13. Extending from the lower end of the legs to theside-bars are diagonal braces 14.,the inner end of each brace beingconnected by a rivet or bolt 15 with a link 16, the opposite end ofwhich in turn is pivoted to the bracket 4. The sidebars are shownprovided with slots 17 through which the connecting bolts between thediagonal braces and the links pass and in which slots such bolts movewhenthe head and. foot are folded. This structure Specification ofLetters Patent.

12 and the lower ends of these logs thus permits the head and foot to befolded in the manner partly shown in Fig, '2 thereby drawing the pivotedlegs upward in such position that the rollers or casters will stillremain on the floor so that in either the form shown in Fig. 1 or theform in which the bed is folded into its folded position, it may bereadily shifted on the same casters under another bed or out of the way.For locking the mattress frame in its normal bed position suitablelocking means is provided, this consisting of locking bolts adapted toproject into openings 18 in the brackets, these bolts being withdrawn bysome suitable spring clip 19 thereby to lower the bed. This folding bed,however. has been proven in practice to be diliicult to manipulate,especially for a woman. and also dangerous in that when the lockingbolts are released the weight of the mattress frame is such that itimmediately falls with a bang to the injury of the floor and not onlythis. but it is likely to iniure the operator tress frame when itsuddenly descends as has been found inpractice to be frequently thecase. Not only this. but it is dillicult for a woman to raise themattress frame back into its normal bedposition owing to the weight ofthe parts. To overcome these difficulties I have provided means wherebythe bed will descend gradually so that there is no liability of itinjuring either the feet of the operator or the floor and whereby alsothe bed can be readjusted into its normal bed position bycomparatirelylittle effort on the part of the operator. This means in the presentinstance consists of a set of springs, four in number, located in aparticular manner so that the object sought will be accomplished. Eachspring in the present instance comprises a col spring 20 having one endsecured to the side-bar and its oppo.'te end secured to the belt whichconnects the diagonal brace and the link, or instead of to the bolt to abent or inwardly extending end 21 of the diago nal brace, as shown inFig. 2. By this Patented Dec. 8,1914.

Application filed April 6, 1914. Serial No. 829,724.

means when the locking bolts are released it has been found that thesprings through their co-action with the side-bars and the sliding innerends of the diagonal braces and links causes the mattress frame todescend gradually and slowly to a certain point, after which it may bepushed down to the floor, the springs thus preventing the descent of themattress frame too quickly and in fact necessitating after the mattressframe has partially descended that it be pushed down the rest of thedistance, and as these springs are under their full tension when the bedis folded it follows that when it is desired to raise the mattress thismay be readily done by very little effort since the springs materiallyassist in the upward movement of the bed frame. Thus the liability ofinjury to the floor or to the operator is entirely avoided, while at thesame time very little strength is now required to lift the heavymattress frame.

I do not make any claim herein to the folding bed structure per 86, asthis is not apart of my invention. I only'claim the means for making thebed practical and permitting it to be operated without danger to theoperator and with increased effectiveness.

1 claim as my invention:
